I'm trying to build tooi, a python mastodon TUI
(https://codeberg.org/ihabunek/tooi), which depends on
pydantic, a python-rust data validation module.
Building with python-3.12, in a venv virtual
environment, invoking `pip3 install .`,
pydantic fails with the message,
Building wheel for pydantic-core (pyproject.toml) ... error
error: subprocess-exited-with-error
× Building wheel for pydantic-core (pyproject.toml) did not run successfully.

Running with the advised
CARGO_PROFILE_RELEASE_BUILD_OVERRIDE_DEBUG=true envar
produces the same output as with no envars.
Reading from a "Platform" dropdown on a target-lexicon
doc page, https://docs.rs/crate/target-lexicon/latest
the supported platforms appear to be
aarch64-apple-darwin
aarch64-unknown-linux-gnu
i686-pc-windows-msvc
x86_64-pc-windows-msvc
x86_64-unknown-linux-gnu
That is, no x86_64-pc-cygwin
